〜わけではない
It is not that 〜わけではない
Meaning
A partial denial — "it is not that ~", "that does not mean ~". Softens rather than rejects outright.
Formation
[plain form] + わけではない · [na-adj] な / [noun] という + わけではない
Notes
Denies an inference the listener might draw, not the fact itself: 嫌いなわけではない ("it is not that I dislike it" — I just do not eat it often). Compare わけがない, which is a flat "there is no way". 〜というわけではない is the fuller, softer form.
